I wan't to drive 8 RGB LED stripes (8 stripes * 3 colors per stripe = 24 channels) with PWM. Each output is driven with a logical level MOSFET. The stripes already have a resistor. I have looked at the TLC5940 and the TLC5942, but a forum post says, you have to set "BLANK" to ground to repeat each PWM cycle, and the ICs are a bit too "big" for this project. Is there a "simple" 24 channel PWM IC out there (SPI or I2C preferred)?
